一种无塔自动供水真空管井
本技术属于钻井
,涉及一种水井,具体是一种无塔自动供水真空管井。
技术介绍
管井是井径较小,井深较大,汲取深层或浅层地下水的取水建筑物。它可以是竖向的﹑斜向的和不同方向组合的﹐但一般以竖向为主﹐可用于生活取水﹑灌溉。目前,常规的管井基本都为敞口式水井,一般是通过抽水设备将地下水抽到地面以上设置的蓄水池、水塔或电控无塔供水系统进行供水,敞口式水井容易落入脏物或是老鼠、蟑螂等污染物威胁饮水安全,地面供水设施占用使用空间,且常规水井在抽水时井内水位自然降落,此时的水补给动力只能为降深形成的水力坡度,致使出水量偏小。
技术实现思路
本技术是针对现有技术的不足而提供一种无塔自动供水真空管井,采用井口密封式的结构,有效防止了有害物、污染物等落入井中,消除饮水安全隐患,通过井管与抽水装置的配合,可将井内取水段与装泵段密封分隔,抽水时把取水段的地下水抽入装泵段,使取水段形成真空增加了管井出水量,并使装泵段中的水压缩井管内空气形成弹性压力水,保证了供水压力和供水量的稳定。本技术所采用的技术方案:一种无塔自动供水真空管井,包括钻孔,在钻孔的中心位置设置井管,在钻孔与井管之间填充止水材料与砾料,通过止水材料可支撑孔壁与井管的稳定,并防止含水层的越流补给造成污染,砾料可过滤进入井管内的地下水;所述井管由取水段与装泵段组成,取水段直径小于装泵段直径,并通过变径接头与装泵段连接,在装泵段内由下往上依次设置抽水装置和供水管,并通过抽水装置将取水段与装泵段密封隔离,使其成为两个 ...
